1 Claim.

Our invention relates to a reversible grain conveyer assembly, particularly for the loading of trucks with grain from an adjacent granary, and for the discharge of grain from the said trucks into elevators and the like, an object of our invention being to provide a device of the character herewithin described which is conspicuously easy to use, being also simple in respect of its component parts and therefore inexpensive to purchase.

A further object of our invention is to provide an assembly of the character herewithin described which has wide limits of adjustability and which will give long service without frequent expenses for maintenance.

With the above more important objects in view and such other minor objects as may appear as the specification proceeds, our invention consists essentially in the arrangement and construction of parts all as hereinafter more particularly described, reference being had to the accompanying drawings, in which:

Figure 1 is a side elevation of our reversible the aforesaid belt extends down to the conven tional power take-off iii.

A telescopic shaft ll extends rearwardly over the truck body it, being universally connected at the front end thereof to the rear end of the stub shaft It, such universal connection being designated by the numeral is.

Our grain conveying assembly is removably secured to the rear wall 23. by means of the adjustable strap 2i which encircles the grain trunk 22, and has hingedly connected thereto, a pin 33 designed to enter the socket 2 3.

At one end of the trunk 22 is a discharge orifice in the form of a short belt 25 at right angles 'to the axis of the trunk, the intake end comprising acage or framework 23 the end of which provides a support for the bearing 21 in which the adjacent end of the conveyer shaft 23 is journalled. It will be seen that the spiral conveyer 29 projects at the intakeend of the trunk to allow for entering the mass of grain. At the intake end also of the trunk, we preferably provide the grain conveyin assembly as seen in the position it would occupy in the loading of a truck with grain from an adjacent granary.

Figure 2 is a detail illustrating our adjustable bracket arrangement connected to the rear wall of a truck equipped with our assembly.

Figure 3 is a side elevation of our assembly in the position it would occupy when discharging grain from a truck.

In the drawings like characters of reference indicate corresponding parts in the different .figures.

Our invention comprises two mainparts, the

power transmission assembly collectively designated with the numeral I; and the conveyer assembly collectively designated with the numeral 2, and proceeding to describe first the transmission assembly, it will be seen that the same come prises a bracket 3 secured to the inner surface of the front wall 4 of a truck 5, said bracket itself embodying a pair of slightly spaced, parallel and vertical angle bars 6, between the'fianges I of which is welded a triangular fish plate 8.

The webs 9 of the angle bars are provided with the slots l0 through which extend bolts H into the front wall 4, the slots providing for vertical adjustability of the bracket 3, as for instance when necessary to tighten the belt 12.

Secured in a horizontal position at the apex of the fish plate 8 is a bearing l3 within which is journalled a stub shaft M, a pulley l5 being keyed to the forward endof the stub shaft from which handle 30 by means of which the trunk may be readily manipulated and moved from place to place in a mass of grain.

The opposite end of the conveyer shaft 28 is suitably journalled for rotation and concentricity by any suitable means at the discharge end of the trunk, a pinion 3| being keyed to the conveyer shaft 28 near the end thereof, which end, it will be seen, projects a short distance. The projecting end of the conveyer shaft 28 is designed for universal coupling with the rear end of our telescopic shaft 2'l, such universal coupling being designated by the numeral 32,

An offset bearing 33 secured in position by the strap 34, carries one end of an external shaft 35 which extends parallel with, but is slightly spaced from the trunk 22. this shaft being less than the length of the trunk, and being supported at the opposite end thereof by the offset bearing 36 attached to the strap 31.

Adjacent the bearing 33, and preferably at the extreme end of the shaft 35 is a pinion 38 in mesh with the pinion 3|, and from all the foregoing it will be apparent that when we wish to discharge grain from the truck body l8, all that is necessary is to unfasten the strap 2l-with the pin 23 attached, reverse the conveyer assembly 2 after disconnecting theuniversal coupling 32 from the projecting end of the shaft 28, and then attach the strap 2| to the trunk 22 at theposi= tion illustrated in Figure 3 and finally fastenin the universal coupling 32 with the free end 39 of the external shaft 35, all as indicated by the accompanying Figure 3.

I1 desired of course, we may provide two separate straps and pins 2| and 23 at the location illustrated in Figures 1 and 3 to avoid the necessity for disconnection and having now described our invention, and since various modifications can be made in the same, and many apparently widely different embodiments thereof made within the scope of the claim appended hereto without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense and we desire only such limitations placed thereon as justice dictates.

What we claim as our invention is:

A reversible grain conveyer for trucks, comprising in combination with asource of power on said truck, a power transmission assembly 20 secured to the front end of a truck body and extending rearwardly thereover, said assembly embodying a supporting bracket on the front wall of said body, a bearing on said bracket, a stub shaft in said bearing having a pulley keyed a telescopic shaft extending over said truck body and universally connected to said stub shaft, a grain trunk having intake and discharge orifices at the ,ends thereof removably secured to the 'rear end of said truck body, a spiral conveyer within said trunk, a conveyer shaft projecting from the discharge end of said trunk, a pinion keyed to said conveyer shaft near said projecting end, said projecting end of said conveyer shaft beingdesigned for universal coupling with the rear end of said telescopic shaft when said trunk is in the position for discharging grain into said truck, an external shaft parallel with said trunk, a pinion in mesh with said first mentioned pinion keyed to one end of said external'shaft, said external shaft being less than the length of said trunk, the opposite end of said external shaft being designed for universal coupling with said telescopic shaft when said trunk is in the position for discharging grain from said truck.
